For patients with more than one MR Conditional implant, it is unclear how to choose appropriate scanning conditions, as interactions between neighboring devices are generally not well characterized. This work assesses how lead electrode heating of an IPG/lead based system can be impacted by the presence of a neighboring IPG/lead based system at moderate distances (~15cm). The results demonstrate that lead electrode heating can either decrease or increase, depending on the relative location of the neighboring device. The potential implication is that established conditions for MR safety of one implant may not be appropriate in the presence of neighboring implant.
